None: no spring ends, clips or straps.

Open Loop: ends which can easily be installed on existing hardware.

Closed Loop: a closed loop which is heald more easily by the mounting hardware.

Clip - No Hole: metal clip on the end of the spring.

Clip - With Hole: metal clip on the end of the spring with a hole in the middle for the mounting hardware. Note: the clip with the hole is only available for the bottom end of the spring.

Gapped vs. Ungapped

PLEASE NOTE: Gapped springs are currently unavailable.

When pushing the ends of a spring toward each other, a gapped spring allows the spring to compress. A spring that is not gapped does not compress.

How to Test for Gapped Springs: To check if your current spring is gapped, see if a piece of paper will slide down between two coils. If there is enough space for the paper to slide between coils without manually separating the coils, your spring is gapped. If your are wrinkling the paper to make it fit, your spring is not gapped.

Are gapped springs better? No, they are neither better nor worse. Some torsion spring systems require that the springs be gapped in order to provide adequate space for the spring to grow as it winds up.
